Standard tests for the rank of cointegration of a vector autoregressive process present distributions that are affected by the presence of deterministic trends. We consider the recent approach of Demetrescu et al. (2009) who recommend testing a composite null. We assess this methodology in the...

Le tourisme est un secteur d’importance dans l’économie française. En 2004, la production de services de tourisme en France a été de 106 milliards d’euro soit plus de 6.5 points de PIB (Direction du tourisme, comptes du tourisme). Ce secteur emploie directement plus de 800 000...

This paper proposes a Near Explosive Random-Coefficient autoregressive model for asset pricing which accommodates both the fundamental asset value and the recurrent presence of autonomous deviations or bubbles. Such a process can be stationary with or without fat tails, unit-root nonstationary...

This paper surveys the literature on multi-step forecasting when the model or the estimation method focuses <i>directly</i> on the link between the forecast origin and the horizon of interest. Among diverse contributions, we show how the current consensual concepts have emerged. We present an...

We evaluate the asymptotic and finite-sample properties of direct multi-step estimation (DMS) for forecasting at several horizons. For forecast accuracy gains from DMS in finite samples, mis-specification and non-stationarity of the DGP are necessary, but when a model is well-specified,...
